Method of transmitting data in a wireless communication system
First Claim
1. A method of transmitting a data block to a receiving device in a wireless communication system, the method comprising:
- transmitting, by a transmitting device, a packet data convergence protocol (PDCP) control protocol data unit (PDU) header compression feedback information,wherein the PDCP control PDU comprises type indication information indicating the PDCP control PDU comprises header compression feedback information,wherein the PDCP control PDU comprises an indicator indicating whether the PDCP control PDU is a control PDU or a data PDU, andwherein the PDCP control PDU does not have a sequence number and is not associated with a PDCP service data unit (SDU).

Abstract
A method of generating a data block to be transmitted from a protocol layer to a receiving side in a wireless communication system, the protocol layer having a header compression function, comprises generating at least one of a control packet which includes control information and a compressed packet generated by header compression for an upper layer data block, and generating a first lower layer data block which includes type indication information and the control packet, if the control packet is generated, the type indication information indicating a type of control information included in the generated control packet.
